Health disparities in military veterans with PTSD: influential sociocultural factors

Health disparities based on sociocultural factors such as gender, race and ethnicity, socioeconomic status, culture, and access to health care can potentially complicate the early diagnosis and effective management of posttraumatic stress disorder (PTSD). Research indicates that among those individuals affected by health disparities, there is a greater burden of illness and disability, higher morbidity and mortality rates, and increased behavioral risk factors. The purpose of this article is to highlight the sociocultural factors that affect the development of PTSD and to publicize health disparities in military combat veterans.     

Do cows belong in nature? The cultural basis of agriculture in Sweden and Australia

Within the now extensive recent literature on cultures of nature, agriculture has received less attention than might have been expected given its threshold role in transforming human relations with the earth and with plants and animals. The concept and practice of agriculture can be understood as central to the emergence and maintenance of the culture/nature dichotomy within Western thought and practice. In this paper we use the comparative cases of Sweden and Australia to examine the differential and contingent positioning of agriculture with respect to that which is understood as nature. Broadly speaking, some parts of agriculture are understood to belong to nature in Sweden through a long history. This is not the case in Australia, where the short agricultural history is positioned in contrast to nature. This affects the way in which biodiversity and environmental protection takes place - in Sweden as part of farming, - in Australia in spite of it. We argue that these cultural differences have been more important than generally recognised in debates over multifunctional agriculture. We discuss the environmental management implications of the two different models in a context made more dynamic by climate change.     

Der Personalverantwortliche als strategischer Partner

Since Ulrich (Human resource champions: the next agenda for adding value and delivering results, Boston, Harvard Business School Press, 1997) shaped the strategic role of HR managers, his concept of an HR business partner has been controversially discussed by researchers and practitioners. Explanations about when and how HR managers act as strategic business partners have found limited attention in the literature. Based on the theory of reasoned action developed by Ajzen und Fishbein (Understanding attitudes and predicting social behavior, Englewood Cliffs, Prentice-Hall, 1980; J Pers Soc Psychol 27(1):41?C57, 1973), we hypothesize a positive relation between personal attitudes as well as subjective norm and the behaviour of HR managers to act as a strategic business partner. Results of the German Cranet survey in 2009 show that expected positive consequences influence the personal attitude, whereas the acceptance of the human resources as well as the existence of an HR strategy within the organisation is positively related with subjective norm. Hence, both attitude and subjective norm positively influence the behaviour of HR managers to act as a strategic business partner.     

Modification of Tukey's additivity test

In this paper we discuss testing for an interaction in the two-way ANOVA with just one observation per cell. The known results are reviewed and a simulation study is performed to evaluate type I and type II risks of the tests. It is shown that the Tukey and Mandel additivity tests have very low power in case of more general interaction scheme. A modification of Tukey's test is developed to resolve this issue. All tests mentioned in the paper have been implemented in R package Additivity Tests.     

On the detection of changes in autoregressive time series I. Asymptotics

Various test statistics are discussed which can be used for detecting changes in the parameters of an autoregressive time series. In this first part of our study, the limiting behavior of the test statistics is derived under the null hypothesis of no change as well as under alternatives. In a forthcoming second part of our investigation, these asymptotic results will be compared to some corresponding bootstrap procedures, and a small simulation study will be conducted.     

Did the escalation of the financial crisis of 2008 affect the perception of immigration-related threats? A natural experiment

In this paper, we apply a natural experiment approach, comparing specific data from the European Values Study prior to and after the escalation of the financial crisis in 2008. The aim is to disentangle the short-term effect of the crisis on the relationship between social vulnerability and immigrant-related threat perceptions for the residents of Luxembourg (natives and foreign nationals). Propensity score matching is used to ensure the balanced composition of the control group and treated group with regard to the observed covariates. The results reveal that vulnerable foreign nationals demonstrated lower perceptions of immigration-related threats after the escalation of the crisis than their pre-crisis counterparts. No significant effect of the escalation of the crisis was found among Luxembourg nationals.
